Genuine Allen-Bradley 1756-SYNCH SynchLink Communication Bridge | ControlLogix – Verified Source
The Allen-Bradley 1756-SYNCH SynchLink Communication Bridge is a mission-critical synchronization module within Rockwell Automation’s ControlLogix platform, engineered for high-speed, deterministic data exchange between ControlLogix chassis in demanding industrial environments. As a legacy yet irreplaceable component in coordinated drive and motion control architectures, the 1756-SYNCH commands a premium on the secondary market — a reality that has made it a prime target for counterfeit and refurbished-as-new substitutes. Buyers sourcing this module from unverified channels risk receiving non-functional units, cloned firmware, or modules with undisclosed repair histories that can compromise entire production lines.
At Konmask, every 1756-SYNCH unit we supply is sourced through verified industrial distribution channels and subjected to our in-house multi-step authentication protocol before dispatch. We stock and supply only genuine, authentic Allen-Bradley 1756-SYNCH modules — never clones, never remarked parts. Our procurement team cross-references each unit’s date code, catalog label, and firmware revision against Rockwell Automation’s official documentation, ensuring that what you receive is exactly what you ordered: a verified, original AB module ready for immediate integration.

Our 4-Step Quality Verification Process
Every 1756-SYNCH unit shipped by Konmask passes through the following verification stages before dispatch:
- Step 1 — Physical Authentication: Visual inspection of catalog label, date code, revision marking, and housing integrity. Labels are cross-checked against Rockwell Automation’s known genuine label formats. Any unit with inconsistent fonts, adhesive irregularities, or mismatched revision codes is immediately quarantined.
- Step 2 — Firmware & Hardware Verification: Where applicable, modules are bench-powered and firmware revision is confirmed via RSLogix 5000 / Studio 5000 device identification. Hardware revision is logged and matched to the catalog label.
- Step 3 — Functional Power-On Test: Each module undergoes a power-on self-test (POST) to confirm backplane communication readiness and absence of fault indicators. Results are logged per unit serial/date code.
- Step 4 — Documentation Package Preparation: Upon request, Konmask provides a Certificate of Conformance (COC), functional test report, packing list with unit identifiers, and Country of Origin (COO) declaration. Photos of the actual unit prior to packing are available on request.
Key Features & Benefits
- Deterministic SynchLink Synchronization: Enables real-time, high-speed data synchronization between multiple ControlLogix chassis — essential for coordinated multi-axis motion and drive control per IEC 61800-7 drive profile standards.
- Fiber-Optic Immunity: SynchLink’s fiber-optic medium provides complete immunity to electromagnetic interference (EMI), compliant with IEC 61000-4 series EMC requirements — critical in high-voltage industrial environments.
- Seamless ControlLogix Integration: Occupies a single backplane slot with no additional power supply required; fully compatible with all 1756 chassis sizes (4, 7, 10, 13, 17-slot).
- Legacy System Continuity: Supports existing SynchLink architectures without requiring controller or drive firmware upgrades, protecting capital investment in installed base.
- Reduced Wiring Complexity: Fiber-optic SynchLink eliminates copper signal wiring between chassis, reducing installation time and long-term maintenance overhead.
- Rockwell-Verified Compatibility: Designed and tested by Rockwell Automation for use within the ControlLogix ecosystem, ensuring interoperability with 1756-series controllers, I/O, and PowerFlex drive systems.
Typical Applications
- Coordinated Multi-Axis Motion Control: Synchronizing multiple ControlLogix chassis in CNC machining centers, printing presses, and web-handling lines requiring sub-millisecond axis coordination.
- PowerFlex Drive Coordination: Bridging SynchLink networks between ControlLogix controllers and PowerFlex 700S/700H drives in multi-drive coordinated applications such as paper mills and steel rolling mills.
- Automotive Assembly Lines: High-speed synchronization of robotic welding and stamping cells where deterministic timing is mandated by process safety requirements.
- Mining & Minerals Processing: Coordinating conveyor drive systems across distributed chassis in harsh EMI-rich environments where fiber-optic immunity is non-negotiable.
- Oil & Gas Upstream/Midstream: Pump and compressor drive synchronization in remote installations requiring reliable, low-maintenance inter-chassis communication.
- Power Generation & Utilities: Turbine governor and excitation system coordination where deterministic data exchange between ControlLogix chassis is required for grid stability compliance.
